Regarding righting... I have a SC 20 and have solo righted it and am 200 lbs. The key is in the shroud extenders which get the hull over center so that the weight of the hull helps right it.

As for issues I think they are pretty good. I'd check the hulls around the dagger wells and the transoms. If they look good then I don't know what else to look at.
